AI Technical Summary
In existing heat pipe-based indirect liquid cooling radiators for servers, the coolant flows relatively smoothly within the flow channel, lacking lateral mixing. This results in insufficient heat exchange between coolant layers at different temperatures, reducing the cooling effect.
A disruptor, including a rotating body and a drive blade, is installed inside the liquid cooling pipe. Through the rotation of the rotating body and the design of the jet orifice, the coolant is made to move radially along the liquid cooling pipe, thereby achieving mixing of the coolant and uniform diffusion of heat in the coolant.
It improves the mixing efficiency of the coolant, allowing heat to spread quickly and evenly throughout the coolant, thus enhancing the heat dissipation effect.

[0002] With the rapid growth of business volume in the information industry, data centers have become increasingly important, becoming one of the most crucial infrastructure projects. Currently, most data centers still use air-cooling technology to cool their power electronic equipment. However, due to the high thermal resistance of air itself, forced air convection cooling is inefficient.

This radiator combines heat pipes with liquid cooling to improve heat dissipation. However, in this radiator, the coolant flows relatively smoothly within the flow channel, flowing axially along the pipe with almost no lateral mixing. There is little heat exchange between coolant layers of different temperatures, resulting in insufficient heat absorption by the low-temperature coolant and reduced cooling efficiency.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0026] Please see Figure 1-7 This utility model provides a technical solution for an indirect liquid cooling radiator for servers based on heat pipes:
[0027] A server indirect liquid cooling radiator based on heat pipe 4 includes a base 1, a support boss 2 formed on the upper surface of the base 1, a liquid cooling part 3 fixedly connected to the upper surface of the support boss 2, a heat pipe 4 disposed inside the liquid cooling part 3, the heat pipe 4 being in contact with the heat-generating surface of the server, the liquid cooling part 3 including a mounting body 302 having mounting grooves 301 formed on both the upper and lower sides, a liquid cooling pipe 303 fixedly connected to the bottom wall inside the mounting groove 301, and a plurality of disruptors 5 disposed inside the liquid cooling pipe 303, the disruptors 5 being able to cause the coolant to move radially along the liquid cooling pipe 303.
[0028] Specifically, by setting up the disruptor 5, the coolant can move radially along the liquid cooling pipe 303, so that the coolant flow layer with a higher temperature near the heat pipe 4 can be effectively mixed with the flow layer with a lower temperature, thereby allowing heat to spread quickly and evenly throughout the coolant and improving its heat dissipation effect.
[0029] The disruptor 5 includes a rotating body 501 rotatably connected to the inner wall of the liquid cooling pipe 303, and the surface of the rotating body 501 is provided with a plurality of drive blades 502.
[0030] The rotating body 501 is in the shape of a hollow sphere, and multiple jet holes 503 are opened on the surface of the rotating body 501.
[0031] The top and bottom of the rotating body 501 are provided with mounting surfaces 504, and a rotating shaft 505 is fixedly connected to the mounting surfaces 504. The inner top wall and inner bottom wall of the liquid cooling pipe 303 are provided with rotating holes, and the surface of the rotating shaft 505 is rotatably connected to the inner wall of the rotating hole.
[0032] Specifically, by setting the drive blade 502, the rotating body 501 can be driven to rotate by force when the coolant is flowing, thereby disturbing the coolant. By setting the jet hole 503, under the action of the centrifugal force of the rotating body 501 and the pressure inside the rotating body 501, some coolant can be discharged from the jet hole 503, improving the disturbance effect on the coolant and strengthening its radial movement in the liquid cooling pipe 303.
[0033] A diversion connector 304 is fixedly connected to the end of the liquid cooling pipe 303. A diversion groove 305 that penetrates the lower mounting groove 301 is opened in the inner bottom wall of the upper mounting groove 301. The diversion connector 304 is connected to the diversion groove 305. A flexible hose connector 6 that is connected to the diversion groove 305 is fixedly connected to the surface of the mounting body 302. A cover plate 306 is fixedly connected to the inner wall of the mounting groove 301.
[0034] Specifically, by setting two hose connectors 6 to connect with the external coolant injection pipe and discharge pipe, the coolant flows inside the liquid cooling pipe 303. The coolant is then diverted to the two liquid cooling pipes 303 by the diversion channel 305 and the diversion pipe. The liquid cooling pipe 303 is flat to increase the contact area.
[0035] The heat pipe 4 includes an evaporation section 401 and a condensation section 402. An insulating section 403 is provided between the evaporation section 401 and the condensation section 402 for connection. Both the evaporation section 401 and the condensation section 402 are flat.
[0036] The mounting body 302 has a receiving groove 307 on its front side, the condensing section 402 is located inside the receiving groove 307, the base 1 has an embedding groove 7 on its lower surface, and the evaporating section 401 is located inside the embedding groove 7.
[0037] Specifically, the evaporation section 401 is in contact with the heat dissipation surface of the server. The heat generated by the server is absorbed by the evaporation section 401. The working fluid evaporates due to heat and forms a gaseous working fluid that flows to the condensation section 402. On the one hand, the gaseous working fluid condenses back into a liquid state and flows back to the evaporation section 401 through the wicking core of the groove structure or composite structure to continue absorbing heat. On the other hand, the heat released by the condensation section 402 is absorbed and carried away by the coolant.
[0038] Working principle: When this server indirect liquid cooling radiator based on heat pipe 4 is used, the evaporation section 401 is in contact with the heat dissipation surface of the server. The heat generated by the server is absorbed by the evaporation section 401. The working fluid evaporates upon heating, forming a gaseous working fluid that flows to the condensation section 402. On one hand, the gaseous working fluid condenses back into a liquid state and flows back to the evaporation section 401 through the wicking core with a grooved or composite structure to continue absorbing heat. On the other hand, the heat released by the condensation section 402 is absorbed and carried away by the coolant. During the flow of the coolant, the drive blade 502 rotates, and the drive blade 502, under the force, drives the rotating body 501 to rotate. This further disturbs the coolant. Under the centrifugal force and internal pressure of the rotating body 501, some of the coolant is discharged from the jet hole 503, which enhances the disturbance effect on the coolant and strengthens its radial movement in the liquid cooling pipe 303. This allows the coolant flow layer with a higher temperature near the condensation section 402 of the heat pipe 4 to effectively mix with the flow layer with a lower temperature, thereby enabling the heat to spread quickly and evenly throughout the coolant and improving its heat dissipation effect. As a result, the server indirect liquid cooling radiator based on the heat pipe 4 has an ideal heat dissipation effect.
